Laser treatments using 532-/1064-nm Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers are popular non-ablative and selective photothermolysis therapies for pigmentary disorders. We treated three male Korean patients (aged 23, 27 and 24 years) for smoker's gingival hyperpigmentation using a 532-nm Q-switched Nd:YAG laser. At each treatment session, the laser was delivered at 1.2 J/cm(2) with a 5-mm spot size and appropriate overlap. Clinical improvement as well as complete healing of the treated gingiva was noted within 2 weeks after each treatment. We also observed that the therapeutic effects lasted more than 6 months.
使用532/1064纳米调Q掺钕钇铝石榴石（Nd:YAG）激光进行的激光治疗是用于色素沉着疾病的流行的非剥脱性和选择性光热解疗法。我们使用532纳米调Q Nd:YAG激光治疗了三名韩国男性患者（年龄分别为23岁、27岁和24岁）的吸烟者牙龈色素沉着。在每次治疗过程中，激光以1.2 J/cm(2)的能量、5毫米的光斑尺寸和适当的重叠进行照射。每次治疗后2周内观察到治疗牙龈的临床改善以及完全愈合。我们还观察到治疗效果持续超过6个月。
